PIANO-STOOL.

SPECIFICATION forming part' of Letters Patent N o. 595,847, datedDecember 21, 189'?.

Application led November 14, 1896. Serial No. 612,118. (No model.)

to provide a device of this kind that can bev adjusted vertically andits seating capacity increased or diminished quickly and readily.

It consists in the novel features of construction hereinafter fullydescribed and specically claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a vertical longitudinal section of a piano-stool constructedin accordance with this invention.

Fig. 2 is a bottom plan view, the feet being removed. Fig. 3 is avertical transverse section.

Referring now to said drawings, 1 indicates the upright post, providedwith feet 2. The said post 1 is provided with a longitudinalguide-opening 3 to receive the sliding spindle 4 of the seat. The saidspindle 4 is provided with notches or teeth 5, that are eny gaged by aspring-actuated detent 6, mounted upon and operated by a rod 7, fastenedto the seat and passing through an eye in said detent. The lower portionof said rod 7 is situated within and extends through an opening in thepost 1 and has a slight lateral play therein, whereby the detent isdrawn away from the toothed spindle. The upper end of this rod 7 isprovided with a handle 8, moving in guides in the lower face of theseat, and by means of which the detent can be operated to raise or lowerthe seat. The seat 8 is provided at its ends with hinged wings 9. Thehinges between these wings and the said seat consist of guide loops oreyes 10, that are situated within guide grooves 11 upon the seat andthrough which extend the guide-rods 12, fastened to the seat andsituated within said grooves 11. In this Way it will be seen that thewings cannot only swing with relation to the seat, but also can moveinwardly,whereby their ou ter faces can stand flush with the ends of theseat when they swing downwardly, as shown in dotted lines in Fig. 1.

Mounted upon the lower face of the seat and Within suitable guides arethe springactuated plungers 13, that serve both to support the wings andto move them to a horizontal position. These plungers consist of slidingframes, the outer or cross piece of which is provided with a stem 14C,that slides at its inner end through a casting 15 upon said seat, whilea spring 16 serves to press these plungers outwardly. 'Ihe wings 9 areprovided with downwardly and inwardly projecting hooks 17, situated toengage the out-er ends of the plungers when they are eX- tended. limitof its movement and the wings in a depending position, a spring-catch 18is mounted upon the lower face of the seat and is controlled by a handle19, near one side of the seat. This spring-catch 18 is situated toengage a projection 2O upon the wing when said wing is in a dependingposition, as shown in dotted lines, Fig. 1. When it is desired to raiseone of the wings, it is necessary only to pull upon the spring-catch 18,which releases the wing, whereupon the spring 16 forces the plungeroutwardly and lifts the wing to a horizontal position, while at the sametime it engages the hook or finger 17 and serves to relieve the hingesof the wings from the strain of a person sitting upon the seat, asclearly shown in Figs. 1 and 2.

In the foregoing description itwillbe seen.

that I provide a piano-stool which can be readily raised and lowered andwhose sitting capacity can be quickly enlarged or decreased.

To hold a plunger at the inward 7o Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the seat, of a 2. The combination with a seatprovided loo 1o upon said seat, and engaged by guide-rods situatedwithin said guide-grooves, substantally as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing Witnesses.

THOMAS CLYNE.
